Description

In experiment C3.5.2.1, an acid-base titration is performed in which a hydrochloric acid solution is titrated with sodium hydroxide. Because hydronium ions and hydroxide ions have very high conductivity, the equivalence point is easy to determine. During the titration, the conductivity falls at first because more and more hydronium ions are neutralised.

Beginning exactly from the equivalence point, it starts to rise again because then there is a surplus of hydroxide ions.
